    1983 -750/ 816 kit jetting questions

    1983 750/816"cc
    i have stock jets in now-37.5 pilot,160 air,122.5 main
    anyone used the 816 kit with stock cams,carbs ,and air box?,header kit
    i got mine together, runs strong, but im wondering what jetting to use
    i have a gsxr header pipe,and a k&n air filter,does run great, plugs are lightly sooty black,not lean,not wet

    if i cover the breather hole slightly it revs great, so im thinking just a bigger pilot,and main jet change?,as its gettin g plenty of air
    i dont want to fiddle with the needle,and i dont think it needs it
    any one know what size will be spot on or close?
    40 pilot, 130 main???
    gurus knowledge needed-
Working...
